To all whom it may" concern Be it known that 1, JAMES INoELLs, a citizen of the United States, residing at Muskegon, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Heaters for Dwellings, of which the following is a specification.

My invention relates to improvements in boilers for use in heatingdwellings, and its objects are: First, to provide an inexpensive boiler that will produce the maximum of heat with the least possible expenditure of fuel. Second, to provide a heating boiler with which the supply of fuel to the grate will be constant. Third, to provide a heating boiler with which the radiation of heat directly from the boiler will be reduced to the minimum. Fourth, to provide a heating boiler with which a long circuit, and a short circuit of heat distribution may be provided, each independent of the other. Fifth, to provide a heating boiler consisting of an outer annular, and an inner cylindrical boiler with an annular smoke and fire flue between them, and, sixth, to provide a boiler of the class named with which the smoke and soot from the burning fuel will be practically all consumed before entering the smoke and gas flue. I attain these objects by the construction and arrangement of parts shown in the accompanying drawing, in which- Figure 1 is an elevation of the boiler and its jacket complete. Fig. 2 is a vertical section of the same on the line w w of Fig. 1. Fig. 3 is a vertical section of the boiler, on the line 3 3 of Fig. 2, with the fire base removed, and showing the outlines of a long circuit and a short circuit pipes, and, Fig. 4 is a cross or transverse section of the same on the line 2 z of Fig. 3.

Similar letters refer to similar parts throughout the several views.

My complete heater consists of an outer metal jacket, as A, an intermediate annular boiler or water jacket E, between which and the jacket A is a space that is designed to be filled with some nonconductor of heat, as indicated at a in Fig. 2, which may consist of a fireproof fabric, as asbestos, of ashes, sand, ground gypsum, or any other fire proof, non-heat conducting material, which is designed to prevent, as much as possible, the radiation of heat from the annular water greatest possible degree of heat may be gen erated in the cylindrical boiler with the least possible combustion of fuel.

The combustion chamber C is located directly below the boilers G and E and, when coal is used, is provided with a coal grate, as C, which derives air for the combustion of the fuel from the openings shown in Fig. 2 through the plate H, that lies between the combustion chamber and the ash chamber D.

Y I represents a fresh air pipe by means of which air entering at the door d, in the ash pit, passes directly up to the apertures 2', see Fig. 2, where it passes out over the fuel grate C, and is madeto pass over the entire surface of the-grate by means of the deflector I, before it can enter the lines F F and be conveyed out of the pipe F, as indicated by the arrows in Fig. 2. By this means the heat is forced to pass upward between the annular water jacket E and the cylindrical boiler G, so that the greatest possible amount of heat is utilized for raising the temperature of the water in the boiler G to the desired degree.

lVater flows into the water jacket from a city main, or from any available source, through the inflow pipe L, and a series of pipes, as g g, connect the water jacket and the boiler so that a perfectly free circulation of water is assured between them.

Coming now to the circulation systems, hot water passing out of the boiler G through the pipe J is designed to pass through a single room and back through the pipe J into the bottom of the boiler G, as at .7 forming what may be called a short circuit, as indicated; while water passing out of the boiler through the pipe K is designed to be carried through several rooms or apartments and back into the water jacket E through the pipe K, which is simply a continuation of the pipe K. The circulation of water through the pipes J and K may be governed byany of the well known devices for governing the flow of water through pipes, and as these devices are common and numerous, and do not enter into my invention I do not deem it necessary to illustrate them, or any of them in this connection.

B B, shown in Figs. 1, 2 and 4, represent coal chutes through which coal or other available fuel may be passed downward into the grate C.

The plate H may be made of cast steel, or other suitable metal, and may be provided with a flange, as h, to which the lower end of the walls of the boiler G may be riveted or otherwise secured to form a water tight joint at the lower end of the boiler.

As the circuit through the pipes JJ is very short the water passing through them does not get so cold but that it may be safely allowed to enter directly into the boiler G, hence l. have provided for entering it at 9', as hereinbefore stated, but water that is forced through the pipes K-K may be made to travel so long a circuit as to become considerably chilled and might affect the circulation badly, and at the same time call to an excessive supply of fuel, if allowed to flow directly into the boiler G, hence i have provided for having it flow into the water jacket E before entering the boiler G, where it will become suiliciently heated before entering the boiler so that it will not affect the temperature of the water in the boiler to any damaging degree.

I find that to place a trap, as J", in the pipe J greatly facilitates the circulation of the water through the short circuit pipe as it wholly averts the danger of the back pres sure from the lower end of the boiler obstructing the free flow of water back to the boiler.

lVhat I claim as new, and desire to secure by Letters Patent of the United States, is:

1. In a heating boiler, a central cylindrical portion and an annular outer portion, arranged to form an annular flue between them, a casing forming a combustion chami ber below the boilers, a fuel grate in said chamber, an air pipe having the lower end below the grate and concentric therewith and extending upward into the combustion chamber, and a disk lying horizontally be tween the top of the air pipe and the bot tom of the central portion of the boiler to cause an annular column of air to be formed above the pipe and pass through the annular flue with the products of combustion.

2. In a heating boiler, a central cylindrical portion and an annular outer portion, arranged to form an annular line the length of the boiler between them, a casing forming a combustion chamber below the boiler, a

fuel grate below said chamber, an air pipe opening below the center of the grate and extending upward into the 7 combustion chan'iber and having radial openings near the top, and a disk at the top of the pipe arranged to form a column of air above said disk corresponding with the annular fine and made to pass through the annular flue with the products of combustion.

3. In a heating boiler, a central cylindrical portion and an annular outer portion, an annular flue between the two portions, a casing forming a combustion chamber below the portions, a fuel grate therein, an air tube concentric with the fuel grate and having the upper end closed and radial openings near the upper end to cause an annular column of air to form and pass througl'i the annular fine with the products of combustion.
